Attrition Rate

Attrition Rate (often called Churn Rate) is a crucial metric that measures the percentage of customers or subscribers who stop using a company's product or service over a specific period. Imagine a business as a bucket you're trying to fill with water (customers). The attrition rate is the size of the hole in the bottom of that bucket. A high rate means you're losing customers as fast as you can find them, forcing the company to spend heavily on marketing just to stay afloat. For a Value Investing practitioner, this is a major red flag. Conversely, a low attrition rate signals a “sticky” business with happy, loyal customers. This often points to a strong Competitive Advantage (or Moat), allowing the company to generate predictable Cash Flows and grow sustainably over the long term. It's not just about losing customers; it's about what their departure says about the fundamental quality and durability of the business.

Value investors are obsessed with finding high-quality businesses that can stand the test of time. The Attrition Rate is one of the best vital signs for a company's long-term health. A low attrition rate is a beautiful thing. It suggests:

• Customer Loyalty: Happy customers don't leave. This satisfaction often translates into a strong brand and pricing power—the ability to raise prices without sending customers running to a competitor.
• A Wide Moat: Why are customers staying? It could be high Switching Costs (it’s a pain to change banks), a superior product, or a unique network effect. Whatever the reason, it's a barrier that protects the company from rivals.
• Efficiency: A business with loyal customers can spend less on marketing and sales. It’s far cheaper to keep an existing customer than to acquire a new one. This leads to higher profitability and a lower Customer Acquisition Cost (CAC).

A high attrition rate, on the other hand, is a leaky bucket that can sink an investment. It signals:

• A Weak Business Model: The company might be competing solely on price, offering a subpar product, or facing intense competition.
• Unsustainable Growth: The company is on a “customer acquisition treadmill,” spending aggressively to replace those it loses. This can mask underlying problems and eats into profits.

Figuring out the attrition rate isn't rocket science. It's a simple percentage that tells a powerful story.

The most common way to calculate customer attrition is: (Customers Lost During Period / Customers at Start of Period) x 100 = Attrition Rate % For example, if a streaming service starts the quarter with 1,000 subscribers and 50 of them cancel their subscriptions, the calculation is (50 / 1,000) x 100, which equals a 5% quarterly attrition rate.

Let's look at “SaaS-y Software Inc.”

1. It started the year with 5,000 business clients.
2. Over the year, 250 clients did not renew their subscriptions.
3. Attrition Rate = (250 / 5,000) x 100 = 5%

This means SaaS-y Software Inc. has an annual attrition rate of 5%. The company needs to acquire at least 250 new clients just to break even on its customer count for the year.

A number like “5% attrition” means nothing in a vacuum. A savvy investor always asks, “Compared to what?”

A good attrition rate is highly dependent on the industry.

• Software-as-a-Service (SaaS): A 5% annual attrition rate might be considered excellent, indicating a very sticky product.
• Telecommunications: Mobile phone carriers often see much higher monthly attrition rates as customers hop between providers for better deals.
• Gyms & Fitness Centers: These businesses famously have very high attrition, as New Year's resolutions fade by March.

Always compare a company’s attrition rate to that of its direct competitors and the industry average. You can often find this information or clues about it in a company's Annual Report or discussed by management during an Earnings Call.

The most important step is to understand why customers are leaving. Is it because of:

• A price increase?
• Poor customer service?
• A new, disruptive competitor stealing market share?
• The product is no longer relevant?

The “why” tells you whether the attrition is a temporary blip or a sign of a terminal decline in the business's competitive position. A great investor digs into the story behind the numbers.

The Attrition Rate is more than just a metric; it's a window into the soul of a business. It quantifies customer loyalty and provides a clear signal about the strength of a company's competitive advantage. For value investors, a business that can hold onto its customers is a business that's built to last. A low and stable attrition rate is often the hallmark of a wonderful company, while a high and rising rate is a clear warning to proceed with caution. Always remember to check the hole in the bucket before you decide to invest.
